JL Audio Quality with an Affordable Price Tag

The new JL Audio JX Series of amplifiers was designed with a specific purpose: to create a high quality amplifier with a moderate price tag. JL Audio created an entire line of JX series amplifiers to provide an amp configuration for everyone. The line includes three monoblock amplifiers, a two-channel, and a four-channel. Each amp is true to the ratings and provides excellent output for your new speakers or subwoofers. In assisting with matching many of the JL Audio subwoofers together, these amplifiers have specific ratings at 3 ohms. For your next audio system, consider the 2011 JL Audio JX amplifiers for an affordable, high quality amplifier.

Power Specifications - Full Range Channels

RMS Power @ 4 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

70 watts x 4 channels
RMS Power @ 2 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

90 watts x 4 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

180 watts x 2 channels

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
JX (JL Audio)
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

AB
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.

Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

360 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
4 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
4 ohms
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
1%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
1 pair
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
High-pass (HP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 200 Hz
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 200 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
100 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
No
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Really surprised at the amount of power coming out of this little amp. 2010 F150 4 door speakers. I have the JL audio 5x7 speakers, very nice and with this amp it has the best sound! it has very good controls for sound quiality and is light enough I could mount very easy. It is sitting in a very small area and never over heats or even gets hot! It is great. Much more affordable then the JL audio HD amps as well.

Very good amp for the money!! Sound is crystal clear! Made my system sound a lot better and I'm only running the front channels at 35 watts and the rear channels at 60 watts. Definitely worth the money if your not wanting/needing to go huge!

Well worth the $$$

September 11, 2014

Bought this amplifier earlier this year, been using it for almost 6 months now, and so far its been an excellent amp, couldn't complain. Sound clarity and staging is amazing, especially at the high end. Bass is good too. It has a strong solid sound, slightly to the warm end. Heavy amp compared to others I've owned. Its rated @ 70watts X 4, but it feels more like 50watts. I've had an RF amp @ 50watts X 4 that put out more power then this one. Well worth the money, but you could do with equally good (or better) amps at a lower price.

JX360

March 22, 2014

The JX360/4 is a good amp in price and looks great in its design i feel the power rating is off tho it should not be a 360/4 if it can't handle the set up that a 300/4 can the JX360/4 is cheaper but weaker than the slash 300/4v2 (i have 2 now was trying to replace them bc I've had the hooked up 1 at a time on my system with no problem had just i had one four four years but got it fix after i sent the JX360/4 back) . All and all the JX360/4 is still good amp with good design just wish JL wouldnt have made them seem better than they are

I bridged the channels of the JL 360/4 into a pair of JL C5-650 speakers in the front doors of my pickup and they sound awesome. The bass is supplied by a JL JX 500/1 amp and a JL 10" truck box. I couldn't be happier.

Good Amp

June 20, 2012

I have this amp hooked up to a Hertz Hi Energy component set in the front (120 watts rms each woofer+tweeter), and JL Audio C2 6 inch coaxials in the back (60 watts rms each speaker). The sound quality: is good... a lot cleaner than lesser brand amps i have tried, but not amazing. The heat: this amp will get surprisingly and unusually VERY hot! The size: is very big, but I prefer for people to look at it and think it has more power. I don't feel it pushes the 180x2 watts when bridged it claims. My front speakers don't struggle with it. OVERALL: I recommend this amp. I have had nothing go wrong with this amp at all. The power is a solid step up front a headunit. I would love to get a nice class d amp like a JL HD or an Alpine PDX but since this is less than half the price of those, I am satisfied with my purchase.

not bad

February 20, 2012

First off, a great looking amp. Next, kinda long, but fine if you have the room. Now, it seems to run a little warm, but thats fine considering its yet to overheat on me, and i dont see it doing so. The tuning is basic, which is convenient. All the terminals are great, very deep which gives it a clean look. Cant go wrong, puts out good power. For the price, ive never had better. At higher power it seems to MAYBE distort a LITTLE, but with the music i listen to its hard to say. If you keep the gains low, you couldnt get it to distort if you tried.
